AHB DEMO SESSION

Are you an engineering graduate with good command on technical skills? Are you a person willing to work in different environment then log on to www.wisdomjobs.com. AMBA AHB Advanced Microcontroller Bus Architecture is an open standard, on chip interconnect specification for the connection and management bid functional blocks in system on chip (SoC) designs. It facilities development of multiprocessor designs with large numbers of controllers and peripherals. AHB is Advanced High PerformanceBus and is part of AMBA, transfer can start with the bus master, by asserting a request signal to the arbiter. Then the arbiter when the master will be granted to use the bus. A granted Master bus starts the transfer with address and control signal. So track your future as Soc Verification Engineer, Digital Verification Engineer, Senior Silicon Engineer, lead IP Engineer and so on by looking into AMBA AHB job interview question and answers given.

FAQ

How many slaves can be connected to AHB?

The AHB is a pipelined system backbone bus, designed for high-performance operation. It can support up to 16 bus masters and slaves that can delay or retry on transfers. It consists of masters, slaves, an arbiter and an address decoder. It supports burst and split transfers.

What is AHB protocol?

AHB is a bus protocol introduced in Advanced Microcontroller Bus Architecture version 2 published by ARM Ltd company. In addition to previous release, it has the following features: large bus-widths (64/128/256/512/1024 bit).

What is Pipelining in AHB?

Pipelining is accumulating the instructions from the processor through a pipeline or a data pipeline.

Why is APB bridge to AHB?

It is required to bridge the communication gap between low bandwidth peripherals on APB with the high bandwidth ARM Processors and/or other high-speed devices on AHB. This ensures that there is no data loss between AHB to APB or APB to AHB data transfers.
